Network Topology

Define Network topology?
It is an arrangement with which computer system or network devices are connected to each other.

Six different network topologies:

• Point-to-point
• Bus topology
• Star topology
• Ring topology
• Mesh topology
• Tree topology

1. Point-to-point

Description:

When there's two devices are connected to each other.

Diagram:

Advantage:

• Fast
• No additional devices

Disadvantage:

• Maximum two devices only
• Cable breaks will affect to the whole network

          2.Bus topology

Description:

All devices share in one cable

Diagram:

Advantage:

• Easy to implement
• Less cable

Disadvantage:

• Slow connection since other computers are connect in one cable
• Others cannot connect when the cable is broken

 

        3.Star topology

Description:

All devices are connected to one hub or switch.

Diagram:

Advantage:

• Easy to manage
• Easy to detect faults

Disadvantage:

• Expensive
• More cable

     

       4.Ring topology

Description:

It past to one by one until it receive the information.

Diagram:

Advantage:

• Fast sending message
• If another host not working,can use another host

Disadvantage:

• Take time to wait 
• Its not privacy since others can read the message

   

       5.Mesh topology

Description:

Host is connected to one or multiple host.

Diagram:

Advantage:

• Faster because there are more cable
• There is many ways to send when others cable is not working

Disadvantage:

• More cable
• Expensive

     6.Tree topology

Description:

Known as hierarchical topology and most commonly use in the topology.

Diagram:

Advantage:

• Fast
• easy to identify when there's network failure

Disadvantage:

• Expensive
